A study of Providence Medical Technology’s Corus posterior cervical stabilization system in anterior cervical discectomy and fusion found it was a better option than ACDF alone for three-level degenerative disc disease, according to an Aug. 14 news release.
Six notes:
1. The randomized controlled trial included 227 patients across 18 U.S. sites and assessed through 24 months. It compared outcomes between standard ACDF and ACDF with Corus, which is designed for posterior fixation with minimal tissue disruption.
2. After 12 months, patients who had tissue-sparing circumferential cervical fusion had a 61% composite fusion success rate. That figure was 17% for ACDF-only patients.
3. At the 24-month follow-up 75% of CCF patients achieved fusion compared to 33% of ACDF patients.
4. The need for revision surgery within 24 months was more than 10 times lower in the CCF group.
5. CCF showed “superior overall safety success” at two years based on fusion success, absence of revision, neurological maintenance or improvement, and NDI score gains.
6. “For the first time, we have Level I evidence demonstrating that supplementing 3-level ACDF with minimally invasive posterior stabilization and fusion not only substantially improves fusion rates, but also drastically reduces the need for subsequent revision surgeries,” Brandon Strenge, MD, lead author of the study said in the release. “This rigorously conducted study, with its comprehensive fusion criteria and inclusive patient population, provides critical new clinical evidence that reshapes how we approach multi-level cervical fusion cases and how we improve outcomes in high-risk patients.”
